platform/x86: uniwill-laptop: Fix crash on unexpected battery event
On devices that have not UNIWILL_FEATURE_BATTERY set, the underlying
hardware might still send the UNIWILL_OSD_BATTERY_ALERT event. In such
a situation, the driver will access uninitialized data structures when
handling said event.
Prevent this by only handling the UNIWILL_OSD_BATTERY_ALERT event when
UNIWILL_FEATURE_BATTERY is set.
